Amplification of acoustic phonons in superlattice

Dompreh, K.A.; Mensah, S.Y.; Mensah, N.G.; Abukari, S.S. (University of Cape Coast, 1970)

The amplification of acoustic phonons in a superlattice in the presence of an electric field cos( ) has been investigated theoretically and numerically by computational methods. The calculation is done in the hypersound ...
Amplification of acoustic waves in armchair graphene nanoribbon in the presence of external electric and magnetic fields

Dompreh, K.A.; Mensah, S.Y.; Abukari, S.S.; Sam, F.; Mensah, N.G. (University of Cape Coast, 2015)

Amplification of acoustic waves in Armchair Graphene Nanoribbon (AGNR) in the presence of an external electric and magnetic fields was studied using the Boltzmann's kinetic equation. The general expression for the amplification ...
Laser stimulated thermal conductivity in chiral carbon nanotube

Twum, A.; Mensah, S. Y.; Mensah, N. G.; Dompreh, K. A.; Abukari, S.S.; Rabiu, M. (University of Cape Coast, 2012-08-04)

An investigation of laser stimulated thermal conductivity in chiral CNT is presented. The thermal conductivity of a chiral CNT is calculated using a tractable analytical approach. This is done by solving the Boltzmann ...
